What TS BAU does
TS BAU GMBH is a German mid-sized specialty construction company and a wholly-owned subsidiary of the THYSSEN SCHACHTBAU Konzern, headquartered in Mülheim an der Ruhr with two operational branches, Niederlassung Jena (Thuringia, ~120 employees) and Niederlassung Riesa (Saxony, ~180 employees), totaling approximately 300 employees and roughly EUR 55 million in annual revenue. The company traces its origins to BAU-UNION Riesa GmbH & Co (1991) and was formed into its current structure through the 2001 merger of PAPE BAU-UNION, Proterra, and Thyssen Schachtbau Rohrtechnik.
TS BAU delivers integrated construction services across five core divisions: road and civil engineering, railway track construction (DB AG-certified), mining (shaft sinking, tunnelling, legacy mining rehabilitation, mine water management), commercial and industrial construction, and demolition with material recycling. Specialized offerings include DVGW-certified pipeline construction, landfill construction across all deposit classes, and turnkey complex projects up to EUR 20 million via the Projects division at Riesa. It also operates a Bauhof (equipment yard) division that supplies dual-gauge excavators, soil stabilization equipment, and proprietary rescue technology including the jointly developed TS-NOT01 mobile rescue winch with OLKO.
The company serves enterprise and government clients through public tenders, direct negotiations, and joint ventures (Arbeitsgemeinschaften). Anchor clients include Deutsche Bahn AG, RAG Aktiengesellschaft, LMBV, Wacker Chemie AG, Feralpi, energy companies for 380kV substation work, and Saxony/Thuringia municipalities. Revenue is generated from one-time project contracts and ongoing service/maintenance agreements, with credentials maintained through a dense stack of regulatory certifications (ISO 9001, ISO 27001, DB AG PQ, DVGW, WHG, § 7 Explosives Act, radiation protection authorization). GTM is enterprise field sales with long, multi-year contract cycles and participation in consortia with Tier 1 firms such as Implenia and Hochtief on flagship tunnel projects.
